Oh, I didn’t read carefully. I ran sudo pacman -Syu.
Now after running sudo pacman -Suu I had to remove tlp because of dependencies. Then I got issues with reinstalling it because the mirrors x32-unstable refused to allow to download it (forgot to copy the exact message, sth with size). Then I noticed that sudo mkinitcpio -P only applied the [base] hook.

This post is a Wiki, anybody can edit it and insert the distro name in alphabetical order.
Since Arch Linux is dropping 32 Bit support (except for multilib packages) and many people asking what next and giving numerous recommedations for distros repeating themselves on and on - I’m creating a central topic to give reference for distros which still support 32 Bit x86 hardware.
Please, don’t add distros which 32 Bit versions you haven’t tested, having tested them on 64 Bit machines is OK! It is …

And I hope this is all somewhere on the manjaro wiki that is fairly easy to find?

Is manjaro32 going to use its own forum category?
…if not where should new issues be posted?

…Have made the transition as described but had to remove tlp for pacman -Suu to work & then add tlp after the update. Having issues with some AUR packages not being retrieved:
ckbcomp is a dependency for manjaro-settings-manager
faenza-green-icon-theme has multiple dependecies
firefox-beta-bin update/install reports no i686 version when it seems to be listed in the firefox index page https://ftp.mozilla.org/pub/firefox/releases/58.0b4/
note: firefox-developer 58.0b4 downloads & installs from AUR & other AUR updates seem to work.

@pjpreilly: Best create a separate topic and include there a link to the original post (to get the link click the chain symbol below the original post). And tag the new topic you create with i686 or manjaro32.

@Orajnam: Hm, machines which need PAE (32bit with >4GB RAM) should be powerful enough to build a PAE kernel. As a byproduct they can get one with -march=native.

@RoestVrijStaal: I would wait with that. Manjaro package versions are still newer than those of archlinux32. If you want to test this alpha stage project you should read
